Refactor sensor example apps to use page.add and append

Updated sensor service example scripts to use page.add for UI controls and page.services.append for service registration, replacing previous usage of page.controls and assignment to page.services. Also removed unnecessary variable declarations and logging setup for improved clarity and consistency.
